Cascade synthetic pathways, which allow multi-step conversions to take place in one reaction vessel, are crucial for the development of biomimetic, highly efficient new methods of chemical synthesis. Theoretically, the complexity introduced by combining processes could lead to an improvement of the overall process; however, it is the current general belief that it is more efficient to run processes separately. Inspired by natural cascade procedures we successfully combined a lipase catalyzed amidation with palladium catalyzed coupling reactions, simultaneously carried out on the same molecule. Unexpectedly, the bio- and chemo-catalyzed processes show synergistic behaviour, highlighting the complexity of multi-catalyst systems.
级联合成路径允许在一个反应容器中进行多步转化,这对于开发仿生的高效新型化学合成方法至关重要。理论上,通过结合过程引入的复杂性可能会改善整体过程;然而,目前普遍认为单独进行各个过程更为高效。受自然级联过程的启发,我们成功地将脂肪酶催化的酰胺化与钯催化的偶联反应结合在一起,同时在同一分子上进行。意外的是,生物催化和化学催化过程显示出协同效应,突显了多催化剂系统的复杂性。
